Humans can discriminate among about 2^12 distinct colors based only on their spectral composition (hue or saturation). However, human languages contain no more than about 2^3 chromatic “basic color terms,” so communication about color is necessarily imprecise.
What is lost in precision, however, is gained in flexibility. Color terms are easily learned, and they serve several cognitive functions, including efficient communication about color, as assessed by information theory, despite variations in lighting and individual differences in visual perception. Languages differ in having 2 to 16 basic color terms, but the lexical color categories they define are remarkably similar.
In this webinar hosted by the Color Technical Group, Delwin Lindsey and Angela Brown from Ohio State University will discuss these variations and regularities using information theory. They also will discuss how human perception and the need for social communication about color worked together to create color lexicons, and how these lexicons might influence human mental representations of color.
Subject Matter Level: Intermediate - Assumes basic knowledge of the topic
What You Will Learn:
• How human language compresses the 12-bit set of colors into a 1- to 3-bit chromatic color code
• How the language code for color varies, yet also shows remarkable similarities, across human languages
• How lexical color categories arise and how they are related to human color perception and societal need for color communication
Who Should Attend:
• Anyone who is interested in color vision
• Anyone who is interested in the efficient representation of color in computer displays to be viewed by multiple kinds of people (international viewers, color deficient viewers)
